#1 Sets his eyes on the record

Good things often come at a great cost. The Fiend’s loss at WrestleMania 36 would be heartbreaking, for sure, but what if this leads to John Cena winning his record 17th title? Fans don't want to see a part-time champion but Cena's reign would be totally different. He needs just one more title reign and it'll make him a record holder in WWE.
If The Fiend loses, Cena could use his victory as a way to get a championship match in WWE. Cena could challenge the winner of Roman Reigns vs Goldberg in one of the pay-per-views succeeding WrestleMania.
Since we have already seen Roman Reigns vs John Cena once, WWE could even book Goldberg to win at WrestleMania. We have never seen his rivalry with Cena and if it happens, it'll be one of the most interesting storylines of 2020. The Leader of the Cenation could win the Universal title for the first time and break Ric Flair's record of holding most world titles in WWE.
